Forklift head device and three-way forklift

Abstract

The invention discloses a forklift head device and a three-way forklift. The forklift head device comprises a carriage assembly which is connected with a forklift body; a bridge frame assembly, wherein the bridge frame assembly is of a box body structure, one end of the bridge frame assembly is connected with the carriage assembly in a sliding mode, the other end of the bridge frame assembly is rotationally connected with an auxiliary lifting frame assembly comprising guide rail channel steel, and the bridge frame assembly provides axial and radial support for the auxiliary lifting frame assembly; and a pallet fork assembly, wherein the pallet fork assembly is arranged on the auxiliary lifting frame assembly in a liftable mode through idler wheels, and the pallet fork assembly and the auxiliary lifting frame assembly are kept to rotate synchronously. According to the forklift head device and the three-way forklift, the auxiliary lifting frame assembly with a rotating function is arranged, so that the pallet fork assembly can ascend and descend along the auxiliary lifting frame assembly and keeps rotating synchronously with the auxiliary lifting frame assembly, and the three-way forklift can adapt to more complex working conditions; and meanwhile, the lateral movement and rotation actions are driven by a gear motor with an electromagnetic brake and an electric cylinder, the actions are stable and impact-free, the control precision is high, the energy consumption is lower, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of three-way forklift equipment, in particular to a forklift head device and a three-way forklift. Background technique [0002] The three-way stacker for forklift is a special attachment that is loaded on the forklift and can perform stacking operations in the left, front and right directions of the forklift when the fork frame is raised or lowered. It is integrated with the fork, and can carry the fork for 180-degree horizontal rotation and lateral lateral movement, so the forklift can directly pick up the goods horizontally without turning, and realize the forklift handling and stacking goods in narrow aisles Ability. Its excellent performance and excellent efficiency greatly reduce the driver's burden and improve the utilization rate of storage space. However, the existing three-way forklift has the following obvious defects during use: [0003] 1. The lifting of the fork is only realized by the mast ...

AI Technical Summary

Problems solved by technology

[0003] 1. The lifting of the fork is only realized by the mast assembly, without the auxiliary lifting frame structure;

[0004] 2. The lateral movement and rotation of the cargo fork are driven by hydraulic cylinders. The hydraulic cylinders have hydraulic shocks when they move, and the control accuracy is poor. At the same time, the hydraulic drive leads to complex matching pipelines, high failure rates, and unsightly appearance
